WHEEL.

To aZZ whom t may concern:

Be it known that I, EDWIN lit. BEEMAN, a citizen of the United States,resident of Minneapolis, county of Hennepin, State of Minnesota, haveinvented certain .new and useful improvements in Wheels, of which thefollowing is a speciiication.

My invention relates to wheels and particularly those of the tractiontype and the primary object of the invention is to provide means forincreasing or decreasing the width of tread of a machine and increasingthereby the traction without the necessity of removing the wheels andsubstituting othersl therefor.,

A further object is to improve the wheel shown and described in LettersPatent of the United States, No. 1,307,035, issuedv to me June 17, 1919.

The invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims.

lin the accompanying drawings forming' part of this specificationre 1 isan edge view, partially in section, of a wheel embodying my invention,

Figure 2 is a side elevation of the same,

Figure 3 is a detail view of one of the U-shaped clips removed from therim,

' Figure t is a detail sectional view showing a slight modiiication,

Figure 5 in a detail View showing a modied construction of the rim andhub,

Figure 6 is a side view of the same,

Figure 7 is a View corresponding to Figure 5, showing anothermodication,

Figure 8 is a side view of the construction shown in Figure 7,

lin the drawing, 2 represents the hub of the wheel. 3 is a gear ring inthis case shown as internal as a preferable construction, though l donot conne myself thereto, connected with the hub by a suitable web 4t.rllhe ring 3 is provided with an annular flange 5 on which a series oflugs 6 are formed at intervals around the circumference of the Harige.These lugs are preferably provided with seats 7 in their oppositevertical faces. 8 represents a rim of suitable widthxhaving thereon alurality of traction ribs consistin preferab y of angle plates 9arranged obliquely upon the peripheral surface of the rim and securedthereto by suitable means, suoli as rivets l Specification of LettersPatent.

10. rllhese ribs are preferably mounted on the rim to extend beyond oneedge thereof, as indicated in Figure 1, thereby to a considerable extentincreasing the tractive power of the wheel.

in the distancebetween the rows. With this end in view l provide aseries of U- shaped clips 11 secured to the inner tace of the rim 8 bysuitable means, such as rivets 12 or bolts 12a. These clips have arallelarms 13 and 13I1 projecting inward y from the inner face of the wheelrim and these arms have end portions adapted to tit the seat 7 of thelug 6 and are provided with holes 14 through. which bolts 15 may beinserted and through similar holes inthe lugs 3 for locking the arms andlugs firmly .togethen From an examination of Figure 1 it is evident thatby changing the adjustment of the clips on the supporting lugs the widthof tread of the machine may be varied to a considerable extent. 1n thefigure, the arms 13il of the clips are shown secured to the outer sfaces of the lugs. rllhese may be secured to the inner face, ifpreferred, making the tread slightly narrower, only amounting, however,to the thickness of the lugs. l have indicated in dotted lines in thisfigure thel extreme or maximum width or tread of the machine,which'could be obtained by mounting the arms 13 on the outer faces ofthe lugs in place of the arms 13a. This would move the wheel rimoutwardly a distance equal to its width, while a corresponding lateraladjustment would be obtained for the traction ribs or cleats. With thisconstruction t adjustments are possible, two for each oiithe arms 13 and13a on the opposite sides of the supporting lugs, all without thenecessity of reversing the rim, it being merely necessary to loosen thebolts and change the osition of: the arms supporting the rim on thelugs.

rlhe arms 13 and 13a may be mounted in various ways on the flange of thegear ring. l have illustrated the lugs as a simple convenient means offastening the arme and the Mld rfi-3 lnb together, but it will beunderstood that this fastening means is susceptible of manymodifications, the essential feature being' the idea of the plurality oflateral adjustments of the rim with respect to the hub to adapt themachine for different widths of tread.

The gear ring and the flange 5 really form in effect an inner rim thatis rigidly mounted with respect to the hub, while the outer rim formingthe tread of the wheel is adjust- -able on the inner rim for varying thewidth of tread of the machine.

In Figure 4 I have shown an inner rim 15 supported by a web- 16 andhaving lugs 17 radiating therefrom, provided with seats 18 for the arms,with c ips which correspond substantially to those described withreference to Figure 1, and which I will designate by the same referencenumeral. The clip,

however, is mounted to project slight-ly beyond the edge of the rim.

The lugs 17 are preferably formed in airs by cutting out the middleportion o the metal and, as shown, the outer lugs overhangy the webconsiderably and allow for a greater range of adjustment for increasingthe Width of tread. A further advantage in having the lugs in pairs isthat the number of adjustments of the clips thereon is considerablyincreased. l

I also prefer to provide a plurality of holes 19 in the clips, makingthem capable of lateral adjust-ment on the rim by removal of the rivets,bolts, or other securing means, all of which construction leads to agreater range of movement of the traction rim with respect to the hub.

In Figure 5 I have shown a rim 20 having lugs 21 formed integrallythereon, preferab y by folding or bending the edges of the rim inwardlytoward the hub and then cutting away the metal to form a series of lugs21.` j

The hub 22 has a gear ring 23 and brackets thereto by suitable means,such as bolts 27. The lugs 21 may be adjusted on either face of the 1u25 and 26, and each lug is thereby capab eof two adjustments on each ofthe hub bracket lugs. In assembling the parts, the lugs 25 and 26 areinserted between the flanges of the rim between the lugs 21 thereof .andwhen properly assembled may be rigidly secured by means of bolts passingthrough both the rim and wheel lugs. j

yI n `Figure 7 I have shown a modificationj whlch consists in providinga continuous annular flange 28 on each edge of the rim, preferably bybending the edges of the rim inwardly, as shown in Figure 8. Brackets'29, preferably of cast metal, are secured te the flange of the hub bysuitable means, such as bolts 30, and are secured to the flan es 28 bysuitable means, such as bolts 31. 'll` e in1 Maaate at lntervals. aroundthe rim, said lugs being spaced apart and havin seats formed thereon, anouter rim having cleats transversely mounted thereon and clipscomprising fiat metal portions' secured to the inner face of said outerrim and provided with inwardly projecting parallel end portions whichare adapted to-fit the seats on said lugs, and bolts passingtransversely through said lugs and the end portions of said'clips 4.forsecuring them together, and the adjustment of the end ortions of saidclips on said lugs varying t e degree or offset of said outer run withrespect to said inner rim.
